Auto coater is ddesigned as a freestanding, totally enclosed unit, with in built cip system. Some salient features of this auto coater include: all ss spray gun chock less in operation with automatic nozzle cleaning system, adjustable spray pattern and atomization control make the application of aqueous, organic solvent based film coating, eudragit coating and sugar solution coating on the tablet enables quick weight build up and uniform coating. The unique perforated coating pan design utilizes a totally enclosed, highly efficient airflow system. This airflow system is used for max drying uniformity and minimum process time. Process air flows through the inlet duct and is directed down and through product bed. The air exits under negative pressure through the exhaust plenum located under the tablet bed. Fully automated rotary valves on inlet and outlet ducts located at technical area controls the quantum of inlet and outlet air as per batch size. Matched solution pump and spray gun optimize the coating process. Highly sophisticated, accurate and precise positive displacement/self-priming peristaltic pump ensures the process stability and quality of the end product. All ss spray gun chock less in operation with automatic nozzle cleaning system, adjustable spray pattern and atomization control make the application of aqueous, organic solvent based film coating, eudragit coating and sugar solution coating on the tablet enables quick weight build up and uniform coating.
